The casing 2 which maybe bolted to the `flange 5.

4 is a platelformed i'th the 4head 3 and rspaced therefrom at 6,:asshown. The plate 4'hasa bearing 7 for the-blower shaft 9, one endy yofwhich engages a plug bearing 8,. and the other is heldin a bearing 10,car- "riedfby'an L-pipe 1l, one end 'of which pipe isthreaded into therearwall of the casing 2 and communicates withV the passage 14 is-closedby a head 3 the casing 2 througl formed by the rear wallfoi' the casingand 1i Aby theintegrallyformedpipe-like wall 12, a removable plug 13being provided for gaining `aecessto the passage 14, fin alinement 'withthe blower shaft.`-The casing 2 has `a passage 15 that communicates withthe exit endlG 'of a Zig-zag carbureter 17, the entrance end 18 of whichis held in communication with the pressure chamber 81, formed an innercasing 19 that houses 'the blower blades 21. inner casing 19 is dividedtransversely 'by a ypartition 20 to `form a chamber for the pipe l1,,the casing' 19, member 2l, and partition 20- being rigidly united toturn .as one.

Upon the shaft 9, between the bearings 7 f and 8 is a sprocket the drumshaft 25 an endless chain 24 passes.

y shaft 25 is heldin a bearing in the head 3' and in afbearing 27 on abracket The l wheel 22, over 'which and y over the sprocket 23 on 28,the drum receiving the"y cable 29 that is connected with the weight 30.A handle (see dotted lines in Fig. l) is provided for winding up thecable on the drum.

The gasolene tank 31 rof the machine is lmounted on the .blower casing2, andhas a hood 32t0 cover fthe bucketwheel 35 that is mounted on ashaft 34that is'held in'a bearing 33 in the tank wall.,` l' Thebuckets3G are ypivoted topins 3701i -fing thereof.

Should fire occurin the room containing the machine, the heat will fuse the soft metall7() of the cutoif 69 and permit the gasolene from the tank-131 toreturn to the underground storage tanks via pipe 67 and thus prevent anexplosion. The fusible plugs of the perforated partition 7 0 aremeltedby the heat and open the passage through the plug 69 to the pipe67 under the conditions stated.

the wheel 35 and have arms 38 to engage the adjustable trip pins 82 onthe inner walls of the hood 32. The trip pins v32 are secured one on therear wall and one on the front wall of the hoodv 32 so that one of thepins 82 will engage one set of buckets and` the other pin 32 will engagethe other set of buckets, one of the -pins 82 beinglocated -in advancelof the other, as shown in Fig.v 4 of the drawings. The trip pins82 areadjustable to tip the buckets at dierent angles and allow only a more orless partial emptycontents of the buckets 36 as the wheel 35 turnsthrough t-he medium of devices hereinafter referred to. The funnel 44 ispiped 46) as clearlyshownin Fig.`2 of the drawl ings. The'pi'pe 45passes through the passage 14 and the 4pipe 11 and has its outlet 47arranged to discharge onto a fan 49 at the mouth of the cap 48 of thepipe`v11.` Thel suction of air past the fan 49 causes its rotation andthe gasolene dropped from the pipe 47 Onto the fan 49 will be vwhirledor` scattered to render it more easily vvolatilized. i p

The regulator casing 50is supported over` the casing' 2 by theintegrally formed pipe sections 51 and 53, which form continua-- tionsof the passages 14 and 15, respectively.l rlhe pipe section 51 has itsbore openingcentrally into the casing 50, while the pipe 53 communicateswith the casing 50 near the outer wall thereof.

A pipe 52 is held centrally within the casing 50 and registers with thecentral opening, while a pipe 54 is held over the opening into the'pipesection 53. f The central pipe 52 extends to near the top of thecasing 50' and carries a hood 5S whose lower edge is cut into Vshapedportions. 59 t0 dip into a tank 56 in the top of the gas bell 55, whichbell has a tube 57 to slip over the pipe 52 and form a bearing for thebell. The pipern 54 extends to near the tcp of the bell 55" when down.The pipe 52 is slitted at the` top to afford communication between theinterior of the hood 58, as shown in Fig. 2 of the drawings. Air isadmitted into the The elevator delivers measured quantities casing 50above the bell 55 through an elbow (bucket-ful) of gasolene'to thefunnels 39 60 having filter screens 61, as shown. and 44, that deliversinto the funnels 39,

The gasolene in the carjoins, ilterscreens 64 being provided for the bureter y17 iiowing down on thecorrugated usual purposes. bottom plates thereof is vaporized by the l65 is a pipe which conveys the gasolene passingair and 'gas currents.from the pump 66 tothe tank 31, the pump The blower` causes air to besucked from 66 receiving its supply from a storage tank the inlet 60into the casing 50` above the (not shown) through a pipe 67 y bell 55under the hood 5S, from which it 68v designates a U-tube or pipe, onearm flows up into the pipe 52, from which pipe 52 of which connects withthe tank 31, while it flows into the passage 14, and from thence theother arm carries a thermallyvopened"l into the pipe 11. As it leavesthe pipe -11 wheel 71 with which a pawl 72 coperates. yThe pawl 72 issecured to a disk 73, having a slot 74, by a bolt 75 whereby the throwof the pawl y72 may be varied to vary the action of the conveyer ,anddeliver predetermined quantities of gasolene to the several funnels 39and 44 respectively. rlhe disk 73 is mounted on a :stub shaft 76 thathas a sprocket 79 around which and karound a sprocket 7S on the drumshaft 25, the drive chain 77 passes. By adjusting the stroke of thepawls 72, the number of buckets-ful of gasolene delivered into therespective fun- Anels 39 and 44 may be varied to suit the workingconditions.

The funnel 39 is piped-up by a pipe 40 with the distributer 41, athrottle. valve 43 being provided after the pipe passes through thebottom 8O of the' gasolene tank 31. A vent pipe 3 4X `is provided forthe tank 31.

The distributer 41 is a trough-like member that is pivoted to the pipe40, as shown in Figs.y 7 and 12, and isprovided with a plurality ofapertured teats through which the contents of the distributor charged,see Figs. 7 and 12. v

Operation: The operator winds up the `cable 29 on the drum 26 and pumpsgasolene into the tank 31,` by the' use of the pump 66, the weight 3()then turning the drum shaft in the direction ofthe arrow in Fig. 1, setsthe blower 21 and elevator 35 into operation.

rlhe elevator shaft 34 carries a ratchet ythrough the capt48 the suckedinto.

whence theblower'forcesiit into the chamber ret'er 17, where it isenriched by gasolene thence into the bell 55,

stopped. Hence proportionately less gas is `delivered to the bell 55.ffull andfair is totally cut the chamber 84 of the'blower 21, from 81.VThe" blower 21 when in operation causes a reduced pressure in thechamber 84,

thus vaporizing the gasolene that emerges from the pipe 47, the Combinedvaporized -1 gaso'lene and air is what passes through the blower intothe chamber 81, where it will be under a positive pressure. The air isforced from'the chamber 81 to the zig-zag carbufroin the distributer 41.The carbureted air then passes into the passage 15 and froml via thepipe 54. ould more gas be generated than is being the bell will the airsupply by' Sh consumed at the burners rise and gradually close offiininersing the openings v59 of the hood 58.,y At this time also a drag'occurs on the blower' 21 thereby slowingit down, and at the same timethe fiow of carbureted air through thel blower and carbureter isproportionatelyl TWhen the bell 55 is ofi", retarding influence lon theblower, will suflice to completely stop the blower and elevator untilthe gals within the bell 55 has been withdrawn' through the pipe 62, andthe air passage is againy open. rlhus it will be seen that my improvedgas generating apparatus is self-regulating, will givea gas of' constantrichness and one in which the air and gasolene 'vapor 'bear a constantrelation to one another.

The zigzag carbureter 17 alone may be used by closing the valve 46,korthe 4rotary carbureter alone may be used by closing the valve 48, orboth carbureters may be used' at the saine time, when both valves 46 and43 are open.` Thus a' gas with but a limited; amount of gasolene vapormay be provided,` or an enriched gas may be formed, as desired.Furthermore the water in casing 2 which is kept in constant circulationby the blower 21, will thereby keep the contents of the chamber 84 andcarbureter 17 at an even temperature. In the practical operation of myapparatus as demonstrated by actual practice and tests and theconditions ordinarily met with in practice, freezing of the water inthechamber 84 does not occur.

y coi-rugating the bottomvwalls of the carbureter 17 the liquid will beprevented from running down along one side orthevy `other should theapparatus not be held' eX- actly level andby pivoting' the distributer'41 any unlevelnessk of the machine will bel compensated. f
